1. Network Block Device client This package contains the client process for the Network Block Device. The Network Block Device is a client/server protocol that emulates a block device (like a hard disk, a floppy, a CD-ROM, ...) over the network, thus giving the system the ability to swap over the network, or to use raw network diskspace for other purposes. Note, however, that it is not possible to access a single networked block device from different clients simultaneously; if you want that, you don't need the Network Block Device (which, basically, is a Disk Server protocol) but something else, like Sun's Network File System (NFS), or CODA.
